At the moment, Cri commands either accept subcommands, or accept arguments (an arbitrary number of them).
Do you need to have a command that can take both? (I imagine that could get confusing.)
from cri.
My use-case is a command configure
with known subcommands (user
, system
, etc.). It's the subcommands that need to take arbitrary arguments -- otherwise I end up with something ugly like
configure user --option=foo --value=bar
configure user --option=format --value-yaml
as opposed to something like
configure user foo=bar format=yaml
This is oversimplified and somewhat contrived, but I hope it gets my idea across.

@RoUS Would something along these lines work?
# frozen_string_literal: true
require 'cri'
config = {
'animal' => 'cat',
'sound' => 'meow',
}
config_cmd = Cri::Command.define do
name 'conf'
usage 'conf [subcommand] …'
summary 'manage configuration'
description '…'
end
set_cmd = Cri::Command.define do
name 'set'
usage 'set key=value ...'
summary 'set config values'
description '…'
run do |opts, args|
args.each do |string|
key, value = string.split('=')
config[key] = value
end
end
end
unset_cmd = Cri::Command.define do
name 'unset'
usage 'unset key ...'
summary 'unset config values'
description '…'
run do |opts, args|
args.each do |key|
config.delete(key)
end
end
end
config_cmd.add_command(set_cmd)
config_cmd.add_command(unset_cmd)
config_cmd.run(ARGV)
pp config
% ruby conf.rb unset animal
{"sound"=>"meow"}
% ruby conf.rb unset asdf
{"animal"=>"cat", "sound"=>"meow"}
% ruby conf.rb set fn=Denis ln=Defreyne
{"animal"=>"cat", "sound"=>"meow", "fn"=>"Denis", "ln"=>"Defreyne"}

Yes, I think that would do it; I totally missed the concept of using #run
in the command definition. Thanks!

Cool! I’ll close this issue now.
